How to level without popping a windshield???

I have Quadra by Big Foot and I would have to rate them the best because you can work them one at a time or all four at a time. It takes me about a minute to level my coach. Dump the airbags first then lower the levelers until each one touches the ground. Then just push the button on the one or two levelers at a time. Just watch the bubble and you are set.

I used to have HWH before on another coach and it was a nightmare with them.
